FR691V Carburetor Fit for Kawasaki Specific FR691V FS691V FS651V FR651V 15004-0829 15004-0985 Carb for John Deere X320 X380 X324 for Husqvarna Z254f

What It Is

This is an aftermarket carburetor designed to replace the OEM Kawasaki FR691V/FS691V/FS651V/FR651V units (part #15004-0829 and 15004-0985). It’s a direct-fit fuel delivery component for air-cooled V-twin engines used in zero-turn mowers and lawn tractors—primarily John Deere X300 series and Husqvarna Z200 series.

Fitment & Compatibility

Before buying, verify your engine’s exact model number (stamped on the valve cover or cooling shroud). This carb fits:

• Engines: Kawasaki FR691V, FS691V, FS651V, FR651V
• OEM part numbers: 15004-0829, 15004-0985
• Common machines: John Deere X320, X380, X324; Husqvarna Z254f (also Z242f, Z248f)
• Deck size doesn’t matter—only the engine model and carburetor number.

Check these:

• Gasket pattern (this carb uses a square metal-flange mount; confirm your intake manifold matches)
• Fuel line diameter (typically 1/4” barb, but verify yours)
• Throttle/choke cable connection type (studs vs. plastic clips—this unit has studs)

This is an aftermarket replacement, not OEM Kawasaki. Quality control varies by batch.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to swap over the solenoid from your old carb if your engine has one (this aftermarket unit usually doesn’t include it). Expect 30–60 minutes.
• Common gotchas: The bowl gasket may be thin—use a dab of grease to hold it in place during assembly. Also, the float height might need adjustment (check with a caliper: 0.15–0.17” from bowl mating surface).
• Quality notes: Metal castings are acceptable, but brass jets can be slightly undersized. If the engine runs lean, swap the OEM jets into this body.
• Return risk: ~10% failure rate out of box (stuck float, debris). Inspect before installing.

Should You Buy It

This carb is a solid budget fix if you’re comfortable with minor tuning and your OEM unit is clogged or warped beyond cleaning. It’s not for professionals who need zero downtime or guaranteed long life—stick with OEM for that. For a DIY homeowner with a dead carb on a 5–10 year old mower, it’s a cost-effective way to get cutting again.
